HEAT-RADIATING DEVICE.

Application filed October 8, 1904.

To all whom it may concern:

Be it known that I, CHARLES H. WAY,

a citizen of the United States, residing at the city of Lansing, countyof Ingham, State of Michigan, have invented certain new and usefulImprovements in Heat-Radiating Devices, of which the following is aspecification.

This invention relates to improvements in heat radiating devices.

My improved heat radiating device is particularly applicable as acooling device for cylinders for gas or explosion engines, and I haveillustrated and described it in that relation in this applicationalthough it is advantageous for use in other relations.

The objects of this invention are: First: To provide an improved heatradiating device which possesses a very large area of radiating surfacecomparatively and is at the same time simple in structure, compact andeconomical to produce. Second, to provide an improved heat radiatingdevice for gas or explosion engines possessing the above advantages.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the means described in thefollowing specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawings forming a part of thisspecification, in which,

Figure 1 is an end elevation of a gas or explosion engine embodying thefeatures of my invention. Fig. 2 is a side elevation of the structureappearing in Fig. 1.

In the drawings, similar letters of reference refer to similar parts inboth views.

Referring to the drawing, the cylinder A is provided with projectingheat radiating flanges or fins A preferably circumferentially arranged.These flanges A are connected by a plurality of bars 64 preferablyarranged close to the outer edges of the fins, as clearly appears inFigs. 1 and 2 of the drawings. These bars not only add to the radiatingarea and capacity of the fins but also serve as effective bracestherefor so that the fins can be made much thinner than would otherwisebe possible, and still be Specification of Letters Patent.

sufficiently strong. The fins A are also provided with a plurality ofperforations a. These perforations also increase the radiating area andcapacity of the flanges allowing the circulation of air therethrough sothat it is effectively brought into contact with all parts of theflanges. The bars a are also so positioned that the currents of airpassing between the flanges are brought into contact therewith.

The cylinder head is provided with radially arranged radiating flanges Band B, the flanges B extending to the center of the head and the flangesB extending only partially across the head, as shown in Fig. 1. Theseflanges B and B are connected by bars I) which serve to brace the sameand also to add to their radiating capacity and also with perforations 6corresponding to the perforations a of the flanges A. The fins are castintegral with the cylinder body.

By thus arranging the parts, I secure a maximum amount of radiatingsurface in proportion to the size of the structure. This surface is sodisposed as to produce the most effective results, and, as beforestated, the radiating flanges are so braced that the liability of thesame being broken is remote.

By arranging the parts as I have heretofore described, I am enabled, asheretofore stated, to secure a maximum amount of radiating surface inproportion to the size of the structure. The radiating flanges or finsmay be made comparatively thin and at the same time are so braced by theconnecting bars or rods that there is no danger of their being fracturedin ordinary use. By making the flanges or fins thin a large number can,of course, be placed in the same amount of space, and by connecting thesame by bars, as described, the radiating surface and capacity is verymaterially increased. The perforations allow the air to circulate freelythrough the fins.

I have illustrated and described my improved heat radiating device indetail as applied to engine cylinders although I desire to remark thatit is applicable for use in other relations as will readily appear tothose skilled in the art to which my invention relates.

I have illustrated and described the application of my invention in theform preferred by me on account of its structural simplicity andeconomy, as I desire to claim the same specifically as illustrated anddescribed, as Well as broadly.

Having thus described the invention, What I claim as new and desire tosecure by Letters Patent, is:

1. A heat radiating device comprising a body portion; a plurality ofthin foraminated heat radiating flanges arranged close together on saidbody; and a plurality of connecting bars for said flanges locatedadjacent to their outer edges, said body, flanges and connecting barsbeing one integral casting.

2. A heat radiating device, comprising a 15 body portion; a plurality ofthin heat radiating flanges arranged close together on said body; and aplurality of connecting members for said flanges located adjacent totheir outer edges, said body, flanges and connecting members being oneintegral casting.

3. A heat radiating device, comprising a body portion; a plurality ofthin heat radiating flanges arranged close together on said body; and aplurality of connecting members for said body, and said body, flangesand connecting members being one integral casting.

In Witness whereof I have hereunto set my hand in the presence of twoWitnesses.
